CLEANING AND SORTING CLAY OR THE LIKE. I

Patented July 9, 1912.

Application filed January 27, 1908. Serial No. 412,907.

To all whom it may concern:

Be it known that 1, MICHAEL Bonn, a subjec" of the King of Austria-Hungary, residing at Nagykikinda, in Austria-Hungary, have invented certain new and useful inprovements in Machines for Cleaning and Sorting Clay'or the Like, of which the following is a specification.

Devices for cleaning and sorting clay are well known which comprise a cylinder containing a mixing and conveying worm and having arranged in its walls perforated sieves with passage openings or meshes of difierent width through which the clay material is pressed out, while stones and coarse admixtures pass into the discharge portion of the cylinder forming a collecting chamber, .and are discharged from the cylinder through an adjustable opening. In the working of these devices it has been found advisable to arrange the sieves or the like on both sides instead of in the well known onesided arrangement, whereby the. length of the device is reduced or its output increased, and the consumption of power reduced. Moreover, practical experience has shown that impurities, coarse admixtures, etc., did not leave the clay purifier through the opening in the bottom of the cylinder, but on the contrary partly remained in the collecting chamber. To avoid this disadvantage, the discharge pcrtion'of the cylinder is provided, according to this invention, with a connection branch, an opening or the like, to which can be attached any desired pump, for instance a well-known boiler test pump, by "iiieans of which a purifying,- liquid (water) is forced through the discharge portion of the cylinder, which is thus cleaned.

A construction of the device according tothis invention is illustrated by way of example in the accompanying drawing, in which Figure 1 is a side elevation'of the appawatus partlyln section and Fig. 2 is a section on a somewhat larger scale on line A-B of Fig. 1.

The device consists of a cylinder 1 in which a worm 2 rotates. On both sides of walls for screening the material, and

the cylinder body are arranged sieves or the like 3 above which are arranged protecting segments 4 (Fig. 2) which are perforatedf The worm 2 is driven by pulleys 5, 6 and by gears 7 8. The rear end of the cylinder 1 is closed by a head 9 in which is arranged a discharge opening 10 for removing the separated stones and other impurities. The said opening can be closed.

According to the invention the discharge portion ll'of the cylinder 1 is made longer than in known devices, so that the stones and the like which have separated from the clay can collect therein. In order to remove the stones, etc., more easily, this part of the cylinder is provided with an opening 12 to which a conduit 13 canbe connected, through which water can be pumped by means of a pump of any desired type through the discharge portion 11 of the cylinder 1.

to secure by Letters Patent is 1. In a machine of the character described the combination of a stationary cylinder having perforated circumferential also having a discharge opening in one of its heads, semicylindrical sieves arranged within said cylinder. on a collecting chamber at one end of the cylinder adjacent to and in communication with said discharge opening, a veying worm arranged longitudinally within the cylinder, means for rotating said worm, a force pump, and a connection communicating at one end with the force pump and at the other end with the collecting chamber of the cylinder.

2. In a machine of the character described the combination of a stationary cylinder, semi-cylindrical sieves arranged in-- teriorly of andon both sides of said cylinder, perforated protecting segments arranged at intervals longitudinally of the cylinder above the sieves, said cylinder having a discharge opening in one ofits heads, a collecting chamber at one end of the cylinder adjacent .to and in communication with said discharge opening, a mixing an both sides thereof,
